The one time I’ve had an issue with our plugs (that would have been solved by something like the British plug design) was when I wasn’t paying attention to a remote antenna resting on top of a loose plug. Accidentally caused a short that melted that little bit of wire but nothing else happened. Just had a black spot on that outlet from then onward.

I have shocked myself on one once but just like with the other person replying that was as a child and felt more like a learning experience to not mess with outlets.
